We will do this in two steps: convert the mass of AlCl 3 to moles and then use the balanced chemical equation to find the number of moles of HCl formed. The molar mass of AlCl 3 is 133.33 g/mol, which we have to invert to get the appropriate conversion factor:

As we just discussed, molar mass is defined as the mass (in grams) of 1 mole of substance (or Avogadro's number of molecules or formula units). The simplest type of manipulation using molar mass as a conversion factor is a mole-gram conversion (or its reverse, a gram-mole conversion).
10 Αυγ 2022 · Convert from mass or moles of one substance to mass or moles of another substance in a chemical reaction. Use a balanced chemical equation to determine molar relationships between substances. The molar mass of any substance is the mass in grams of one mole of representative particles of that substance.
7 Αυγ 2022 · Here is the conversion factor: Grams = Moles x Atomic Mass g = mol x (g/mol) Here are the steps for converting moles to grams: Start with the number of moles and the chemical formula of the substance. Find the molar mass of the substance. Add together the atomic mass of each element multiplied by its subscript.
The simplest type of manipulation using molar mass as a conversion factor is a mole-mass conversion (or its reverse, a mass-mole conversion). In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units (or, conversely, mass units into mole units).
The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. The molar mass of an element (or compound) is the mass in grams of 1 mole of that substance, a property expressed in units of grams per mole (g/mol) (see Figure 4).
11 Μαΐ 2023 · We use the molar mass (mass of one mole) of the substance to convert between mass and moles. When writing calculations, we denote the molar mass of a substance by an upper case “M” (e.g. M (Ne) means “the molar mass of neon”). As always, “n” stands for the number of moles and “m” indicates the mass of a substance.
